HEALTH HAZARD DATA
A very toxic substance causing nausea, vomiting, coldness of limbs and unconsciousness. It is an eye and skin irritant and harmful when inhaled.
HANDLING and GENERAL PRECAUTIONS
Use a fume hood.
Avoid skin and eye contact.
Avoid ingestion, very toxic.

Ingestion wash out the mouth with water and give two to four glasses of water to drink. Induce vomiting by touching a finger to the back of the throat. Obtain immediate medical attention.
Store in a cool, dry atmosphere away from heat.
Rubber gloves, self contained breathing apparatus and laboratory coat.
Eliminate all sources of ignition. Absorb on paper towels or with vermiculite. Place on an iron, glass or plastic dish in a fume hood. Allow to evaporate. burn the paper or vermiculite. Wash the site with a soapy solution.
PACKAGE LOTS: Either
1. Pour on to vermiculite, sodium bicarbonate or sand-soda ash mixture (90/10). If a fluoride is present, add slaked lime to the mixture. Mix and shovel into paper boxes. place in an open incinerator, cover with scrap wood and paper then ignite with a torch or fuse. Stay on the upwind side.
2. Dissolve in a flammable solvent. Spray into a fire box of an incinerator equipped with an afterburner and scrubber.
